```
@Nullable
Object getElementOrNull(ArrayData array,
                        int pos)
```
    Converters and serializers always support nullability. The NOT NULL constraint is only considered on SQL semantic level but not data transfer. E.g. partial deletes (i.e. key-only upserts) set all non-key fields to null, regardless of logical type.
